My pet peeve (besides people who pull out in front of me) is red light runners. They seem particularly bad at the corner of Ranolf and Amohau Sts in Rotorua.
What's worse, it's often hulking great trucks slamming through the intersection up and down Amohau St at what seem like open road speeds.
Nearly every time I approach that intersection, I see at least one vehicle hooning through while a green light is staring back at my line of traffic.
